The new Shimano Poly cables have much less friction than their PTFE 7900 cables, as well as most any other shift cables.

The coating doesn't bunch up like it does on other coated cables, so it remains very slick for a long time.

Last year I was at a Park Tool Summit Clinic and they had 4 Orca's built with 9000 DA, only difference being the cables, and no mechanic there doubted the overwhelming lack of friction on the bike with 9000 cables.

Admittedly I've only been on the system for three months, but the polymer cables and appropriate housing run through Ultegra 6800 shifters and derailleurs has been working brilliantly for me. Much lower friction and zero issues. The polymer itself does get scuffed up at the ends if you aren't careful, but has had no appreciable difference on shift quality.

LOLWOT?

Let's think about this for a second; the Dura Ace 9000 cables are snapping due to a cable routing issue putting excessive stress on the bend which sits inside the shifter, which causes grossly accelerated wear.

Di2 uses electronic cables to send an electronic signal from the shifter to the front / rear mech. The electrical cable does not move, and is not subject to any friction / stress as part of the standard operation.

Asking because I recently upgrade my components from 6800 to 9000 (going to put the 6800 components on the TT bike). Didnt buy the shifters yet though. Ignoring price, cable snapping and weight, are the 9001 shifters better than the 6800 shifters in any way?
